(Cl. 12--33) l 2 This invention refers to apparatus for the In the drawingsl manufacture of shoes, especially for the manu- 1Eig. 1 shows an elevation of an apparatus made facture of such shoes as are known by the name of glued shoes, and more particularly to pneumatic apparatus or presses for gluing the sole in the manufacture of glued shoes.

Thus far, in connection with known apparatus, it is required to employ special devices for each case in the gluing of the sole of the shoes made according to that system, and, in fact, plain shoes for children and men require the masses of gluing to be of a certain type and shape; which type and shape have to be different in the case of low-heeled shoes for gentlemen and ladies; and they also have to be different for the manufacture of ladies high-heeled shoes, it being required by makers to have a set of plates to be changed on their respective machines. With the improved device of my invention, the advantages of which will be easy and immediate to appreciate by experts, the inconveniences pointed out will be entirely eliminated, in view of the fact that the plate or surface supporting the pressure of the shoe on the pneumatic cushion, supplies over the` Zone of the heel such height as may be had by the last of the different kinds of shoes above mentioned. The curved space between the heel and the floor; that is to say, the hollow portion of the shank, is filled by the pneumatic chamber through the force of air and the pressure of the shoe with its last.

From above, it will be seen that the main object dinal section showingl the structure of the invention is to provide a press for the manufacture of the glued-shoe, which constitutes an improvement, having the advantage of being provided with means whereby the same apparatus can be used for the manufacture of mens and childrens glued shoes requiring a level plane, and womens shoes provided with the highest heels in use, inasmuch as the portion correspending to the heel in the said apparatus can be raised to any height required by the last of the shoe.

In the present device of my invention, the point of the shoe can distinctly be put either forward or backward, by simply changing the position of the respective bridges or holders.

These and other advantages, details and features of the apparatus of my invention will become evident from the following description, as well as from the attached drawings accompanying it by way of illustration, the same reference characters being used to show the same p0rtions of the two figures shown.

in accordance with my invention, the surface or plate over placed being shown complete, and its longitusupporting the said plate as well as the mechanism raising the backward half of same, and

Fig. 2 is a conventional detail in perspective of the mechanism used to raise the backward half of the plate for the gluing in accordance with this apparatus.l

Before proceeding to the description in a detailed manner of the apparatus invented by me, I wish it to be well understood that the drawings illustrate only by way manner in which this invention is practised, for which reason the invention is not restricted exclusively to the specific details herein illustrated and described. It is possible, therefore, to make changes and ment and form of its parts, to meet the requirements made necessary by practice, without deviating from the principles and scope of` my invention and, of course, within the attached claims.

As shown in attached drawings, the present apparatus consists of plate I0, divided into forward portion II and backward 'portion I2 by the Zone of the heel of shoe I3, in process of manufacture.

Both portions II and l2 are joined at their lower en'd by means of hinge I4 or the like, whereby the said portions will have a radial motion, they being able yto be raised until they less obtuse angle, or, plate III may be disposed in the apparatus herein described from an entirely plane and straight position to an angular form, be employed in the manufacture of the highest heels.

On the sides of plate Ill formed by portions II and l2, two of which correspond to each of these portions, there are pieces or flanges I5 and I5, one of whichis disposed on each side of the said portion, to which become attached the bridges or pressure arches I1 and I8, which freely slide upon the said guide pieces. Bridge I'I can be provided with a shield I9 so as not to damage the cap of shoe I3.

neumatic cushion 2B fits over portions I I and l2. of plate IB, and prefectly covers ,the gap between both portions, the same as the gap formed by the curved space between the heel and the tread ofthe shoe, at the shank. This cushion is inflated by passage 2| and valve 22, which regushoes having which the pneumatic cushion is of example the preferredl alterations in the arrangewith a sufficient grade to to crosspiece 30 which is also attached to lever 3l, the upper surface of which butts against and pushes portion I 2 of plate I0 so as to raise it at will, as required by the type of shoe made.

matic cushion. Lower lid 33 is attached to surface 32 by means of screw 35 or the like. A

Having thus described the invention what I consider as new and desire to secure by Letters Patent is:

1. An Vapparatus for pressing soles to shoes comprising a plate, a pneumatic cushion resting on said plate, said plate being divided into two hingedly connected portions whereby one portion plate portion.

2. Apparatus soles, comprising a support, a pair of pad Sup- REFERENCES CITED The following references are of record in the le of this patent: i
